The 2020s are “the energy storage decade,” and the world will surpass a terawatt-hour of installations by the time they are over, according to predictions made by analysts at BloombergNEF.

Battery capacity has started to come online at what is claimed to be the world’s largest project to combine solar PV and battery storage at the same site, in California. 

Stem Inc has reported a year-on-year revenue increase of 334% and its first-ever quarter with positive gross margin (GAAP).

Two pumped hydro energy storage (PHES) projects at very different stages of development in Hawaii and Wyoming would enable hundreds of additional megawatt-hours of clean energy use in each region. 

News in brief from around the world in energy storage.

The government of Alberta, Canada, has announced that CA$25 million (US$20.1 million) in financial support has been offered for solar-plus-storage and pumped hydro energy storage as part of a CA$176 million package that will also give funding to oil and gas industry projects. 

The installed cost of solar PV, solar-plus-storage and standalone battery energy storage in the US was reduced across all market segments between 2020 and 2021, with the biggest drop seen in the utility-scale segment. 

A community engagement event was hosted last week for a solar-plus-storage project under construction in Denton County, Texas, pairing 275MW of solar PV with 125MW of battery energy storage. 

ENGIE will no longer proceed with a grid-scale solar-plus-storage project it was awarded in Hawaii, cancelling its order for 240MWh of battery storage from technology provider New HOrizons Ahead (NHOA).
